The NCBI Entrez Genome Project database is intended to be a searchable collection of complete and incomplete (in-progress) large-scale sequencing, assembly, annotation, and mapping projects for cellular organisms. The database is organized into organism-specific overviews that function as portals from which all projects in the database pertaining to that organism can be browsed and retrieved (see Figure 1). For example, you will find all information regarding the human genome project on this project page. (Although the Entrez Genome Project database does not include organellar-, phage-, plasmid-, or viral-only genome sequencing projects, data from those projects are submitted to GenBank and are available in the Entrez Nucleotide and Entrez Genome databases. Sequences such as the human mitochondrial sequence will be attached to the human genome project. There is also a special set of resources at NCBI dedicated to Viral Genomes. Registration not required.
